החדר נראה קטן יותר בלילה.

• החדר = the room
• נראה = looks / appears / seems
• קטן = small
• יותר = more
• בלילה = at night / in the night

So literally, the sentence is something like: The room appears more small at night, which in natural English becomes The room looks smaller at night.

The prefix ה־ is the Hebrew definite article, meaning the.

• חדר = room
• החדר = the room

Unlike English, Hebrew attaches the directly to the noun instead of writing it as a separate word.

Because נראה here means seems / appears / looks, not sees.

This is a very common point of confusion:

• רואה = sees / is seeing (from the verb לראות, to see)
• נראה = seems / appears / looks or sometimes is seen

In this sentence, החדר נראה קטן יותר means the room looks smaller or the room seems smaller.

So the room is not doing the seeing. It is the thing that appears a certain way.

Yes. נראה here is present tense.

Hebrew present-tense forms often work like English looks, seems, or is looking depending on context. In this sentence, the best translation is looks or seems.

Because Hebrew present tense agrees with gender and number, נראה is the masculine singular form.

Because it agrees with החדר, and חדר is a masculine singular noun.

In Hebrew, adjectives and many participle-like present-tense verb forms agree with the noun in gender and number.

So:

• masculine singular: נראה
• feminine singular: נראית
• masculine plural: נראים
• feminine plural: נראות

Since החדר is one masculine noun, נראה is the correct form.

For the same reason: חדר is masculine singular, so the adjective must match it.

• masculine singular: קטן = small
• feminine singular: קטנה
• masculine plural: קטנים
• feminine plural: קטנות

So:

• חדר קטן = a small room
• דירה קטנה = a small apartment

In your sentence, החדר נראה קטן יותר = the room looks smaller.

Hebrew usually forms the comparative with:

adjective + יותר = more + adjective = -er / more ... in English

So:

• קטן = small
• קטן יותר = smaller / more small

Other examples:

• גדול יותר = bigger
• יפה יותר = more beautiful / prettier
• מהיר יותר = faster

Even though English often uses -er, Hebrew normally uses יותר.

Because Hebrew, like English, can leave the comparison implicit.

In English, The room looks smaller at night does not have to say than during the day. That comparison is understood from context.

The same is true here. קטן יותר means smaller, and the sentence leaves the comparison unstated. The implied meaning is usually something like:

• smaller than in daylight
• smaller than it does during the day
• smaller than usual

If you wanted to state the comparison explicitly, Hebrew could add מ־ (than/from), depending on the structure.

בלילה literally breaks down as:

• ב־ = in / at
• לילה = night

So בלילה means at night or in the night.

In natural English, at night is the usual translation.

This ב־ prefix is very common:

• ביום = during the day / by day
• בבוקר = in the morning
• בערב = in the evening

Yes, בלילה can move, but the given order is very natural.

Current order:

• החדר = subject
• נראה = looks/seems
• קטן יותר = smaller
• בלילה = at night

This is a straightforward, neutral structure:
The room looks smaller at night.

You could also say:

• בלילה החדר נראה קטן יותר = At night, the room looks smaller

That version puts more emphasis on at night.

Hebrew word order is somewhat flexible, but not random. Moving elements usually changes emphasis or style rather than core meaning.

All three can work, but looks is probably the most natural here.

• החדר נראה קטן יותר = The room looks smaller
• It can also mean The room seems smaller
• Or more formally, The room appears smaller

The best choice depends on tone:

• looks = most natural in everyday English
• seems = slightly more abstract or interpretive
• appears = a bit more formal

In ordinary conversation, looks smaller is usually the best match.

Then both נראה and קטן would change to feminine forms.

For example:

• הדירה נראית קטנה יותר בלילה.
• The apartment looks smaller at night.

Changes:

• החדר → הדירה because apartment is feminine
• נראה → נראית
• קטן → קטנה

This is a good example of Hebrew agreement: the descriptive words have to match the noun’s gender and number.
